Abstract
(EN) The present invention relates to an olefin-based polymer satisfying the requirements of: (1) a melt index (MI, 190 °C and 2.16 kg load conditions) of 1.0-10.0 g/10 min; (2) a density (d) of 0.875-0.895 g/cc; (3) 0.5 J/g≤dH(100)≤3.0 J/g and 1.0 J/g≤dH(90)≤6.0 J/g as measured by a differential scanning calorimetry precision measurement method (SSA); (4) 15≤T(90)-T(50)≤30 and 50 °C≤T(50)≤75 °C as measured by a differential scanning calorimetry precision measurement method (SSA); and (5) the melting point (Tm), as measured using a differential scanning calorimeter (DSC), satisfies 55 °C≤Tm≤80 °C. The olefin-based polymer according to the present invention, which is a low-density olefin-based polymer, exhibits high mechanical rigidity due to the introduction of high-crystalline regions.
(FR) La présente invention se rapporte à un polymère à base d'oléfine satisfaisant les exigences suivantes : (1) un indice de fluidité (MI, conditions de 190 °C et charge de 2,16 kg) compris entre 1,0 et 10,0 g/10 min ; (2) une masse volumique (d) comprise entre 0,875 et 0,895 g/cc ; (3) 0,5 J/g ≤ dH(100) ≤ 3,0 J/g et 1,0 J/g ≤ dH(90) ≤ 6,0 J/g tel que mesuré par un procédé de mesure de précision de calorimétrie différentielle à balayage (SSA) ; (4) 15 ≤ T(90)-T(50) ≤ 30 et 50 °C ≤ T(50) ≤ 75 °C tel que mesuré par un procédé de mesure de précision de calorimétrie différentielle à balayage (SSA) ; et (5) le point de fusion (Tm), tel que mesuré à l'aide d'un calorimètre à balayage différentiel (DSC), satisfait à 55 °C ≤ Tm ≤ 80 °C. Le polymère à base d'oléfine selon la présente invention, qui est un polymère à base d'oléfine de faible densité, présente une rigidité mécanique élevée en raison de l'introduction de régions hautement cristallines.
(KO) 본 발명은 (1) 용융지수(MI, 190 ℃, 2.16 kg 하중 조건): 1.0 내지 10.0g/10분; (2) 밀도(d): 0.875 내지 0.895 g/cc; (3) 시차 주사 열량계 정밀 측정법(SSA) 측정시 0.5 J/g≤dH(100)≤3.0 J/g이고, 1.0 J/g≤dH(90)≤ 6.0 J/g; (4) 시차 주사 열량계 정밀 측정법(SSA) 측정시 15≤T(90)-T(50)≤30이고, 50℃≤T(50)≤75℃; (5) 시차 주사 열량계(DSC)로 측정한 용융점(Tm)이 55℃≤Tm≤80℃인 요건을 만족하는 올레핀계 중합체에 관한 것으로, 본 발명에 따른 올레핀계 중합체는 저밀도 올레핀계 중합체로서 고결정성 영역이 도입되어 높은 기계적 강성을 나타낸다.
